Commuter Mary Hammett rides a transport module that zips down what many call “I-95.” It moves faster than most cars. Hammett relaxes in the back and pulls out her iPhone, which automatically logs in to the module’s WiFi network.

She taps open the Pandora app and gives the James Fortune station a thumbs up -- a 'like' button on the little screen. As Hammett travels to her downtown Miami office, it's all smooth sailing and silky gospel vocals.
